Former horse trainer Mark Davies told colleague Mick Tubman he won $12,000 from a bet on one of Mr Tubman's horses during Melbourne Cup week months before traces of EPO were found at a Wollongong stable, a racing inquiry has heard. Mr Davies failed to appear in front of Racing NSW stewards on Monday to give evidence into the discovery of bottles containing metabolites of EPO, which led to small-time trainer Mr Tubman pleading guilty to two counts of possessing the prohibited substance on his property. But the 72-year-old Kembla Grange horseman insists he has no idea how they came to be in a fridge on his Wollongong complex, in which hobby trainer Mr Davies also previously rented boxes.

Former horse trainer Mark Davies told colleague Mick Tubman he won $12,000 from a bet on one of Mr Tubman's horses during Melbourne Cup week months before traces of EPO were found at a Wollongong stable, a racing inquiry has heard.

Mr Davies failed to appear in front of Racing NSW stewards on Monday to give evidence into the discovery of bottles containing metabolites of EPO, which led to small-time trainer Mr Tubman pleading guilty to two counts of possessing the prohibited substance on his property.

But the 72-year-old Kembla Grange horseman insists he has no idea how they came to be in a fridge on his Wollongong complex, in which hobby trainer Mr Davies also previously rented boxes.

The inquiry heard that the source of the prohibited substance may have been a person associated to Mr Davies.

Stewards heard evidence Mr Davies boasted to Mr Tubman he had collected $12,000 from a bet on the Mr Tubman-trained Red Henno after it won a race at Hawkesbury during Melbourne Cup week last year.

But stewards could find no record of such a large winning, insisting their own examination of betting records shows Mr Davies winning just "one twentieth" of that amount.
